EISA (Public Law ) was signed by President Bush on December 19, 2007 and will become effective on December 19, Beginning on December 19, 2010, motor manufacturers may not build motors with a lower nameplate efficiency than EISA allows. EISA applies to both NEMA frame motors and the equivalent IEC frame motor. Motors that are built before December 19, 2010 but are held in inventory or are in transit can be sold, this deadline applies only to build dates. EISA Basics General Overview of Levels  General Purpose NEMA & IEC motors that today need to meet EPAct efficiency, will need to meet the NEMA Premium ® efficiency levels (Table 12-12) beginning on December 19, 2010  General Purpose NEMA & IEC motors that were exempt from EPAct because of voltage, mounting, etc. will need to meet EPAct efficiency (Table 12-11) beginning on December 19, 2010  NEMA & IEC motors that are not considered “General Purpose” (i.e., motors that cannot be used in most applications, such as special shafts, blowers or nonstandard frequencies, nonstandard volts/Hz) remain exempt from EISA regulations for efficiency.

On March 31, 2009, the U.S. Senate Energy and Natural Resources Committee adopted a provision that creates a motor rebate program for premium efficiency motors, known as the “crush for credit” program. This proposal passed the House of Representatives but did not go before the Senate for voting. It is possible that a form of the proposed rebates below could still go before the Senate but it has not yet. Proposed Rebates $25 per horsepower for the purchase of NEMA Premium motors Must demonstrate evidence that the user purchased an electric motor that meets the new requirements to replace an installed (existing) motor. $5 per horsepower for the disposal of the old inefficient motor Must demonstrate evidence that the entity removed the installed motor from service and properly disposed of the old motor and nameplate. It is intended to offset the cost of purchasing a new, more efficient motor and to encourage the purchase of higher efficiency motors instead of repairing older, less efficient motors. Details regarding acceptable “evidence” of purchase and disposal have not yet been defined. Rebates

Amps" on the blank line of the nameplate. Motors that would need to meet EPACT because of mounting or other features A spread voltage rating of v would require compliance to EPACT efficiency (Table 12-11) at both 208v and 230v A spread voltage rating of /460v would require compliance to EPACT efficiency (Table 12-11) at 208v, 230v and 460v.

Examples of EISA Rules Example #1: Motor ABC is an EPACT motor (12-11) with rating 100hp 230/460v, 60Hz, 405T 1800rpm, TEFC, standard bracket, horizontal, rigid base. Beginning on December 19, 2010 it can no longer be sold because it is a General Purpose NE MA motor and will not meet the efficiency requirements under EISA. EISA requires that this model must meet NEMA Premium efficiency standards. Increasing the efficiency of this motor would require a design change. Example #2: Motor XYZ is the same as ABC except it has space heaters and a special 13.75” shaft extension. The special shaft extension makes motor XYZ exempt from the EISA requirements, therefore, it can continue to be purchased after December 19, 2010 without a design change or a substitute motor.

Higher efficiency motors: 1) Reduce the operating costs and less stress on utilities, supporting Green initiatives. 2) Generally operate at a lower temperature and for every 10°C reduction in operating temperature, insulation life doubles. 3) Are generally quieter (smaller fans). 4) Have lower vibration with lower bearing temperatures for longer bearing life. 5) Earn a rebate. Comparison of Operating Cost: Example: 100hp 1800rpm ODP motor Operating 24 hrs/day, 240 days/year at a cost of $0.08 per kW-hr Standard efficiency motor with 93% versus NEMA Premium motor with 95.4% Standard efficiency motor uses $36,963 worth of electricity per year to operate NEMA Premium motor uses $36,033 worth of electricity per year to operate In addition to direct energy cost savings, maintenance and downtime will be reduced. Why Should I Upgrade? Over a 20 year life this is $18,600

Our Sales and Engineering teams can help ensure compliance with the new EISA requirements and with your own internal energy initiatives: 1.We will compile a list of the motors that you purchased in the last 12 months. 2.We will help analyze the cost and benefits of upgrading each motor. 3.We will match those models to the new model number. 4.For motors that do not yet have a new model with all of the same features, we will work with you to establish the new model. For special motors that will still be exempt under EISA, consider upgrading to save operating cost over the life of the motor. Some applications may have size, weight or performance constraints - - now is the time to consider these special conditions. Watch for other innovative solutions from your motor energy saver, Marathon Electric!
